4 Claims. (01. 36-34) This invention relates to means for securing heelsto shoes and has for its object to provide a construction simple inparts, more efficient in use, and less costly to apply, than thoseheretofore proposed.

With these and other objects in view the invention resides in the noveldetails of construction and combinations of parts more fully describedhereinafter and particularly pointed out in the claims.

Referring to the accompanying drawing forming a part of thisspecification and in which like numerals designate like parts in all theviews.-

Fig. l is a vertical sectional view through the heel of a shoeillustrating the application of this invention;

Fig. 2 is a top plan view of the heel before it is applied to the shoe;

Fig. 3 is a top plan view of the locking plate associated with the heelsecurement; and

Fig. 4 is a cross sectional view of said plate taken as on the line 4-4of Fig. 3 and looking in thedirection of the arrows. I

In order that this invention may be better understood it is said thatheretofore there has been experienced considerable difliculty,particularly in the case of ladies shoes and slippers, in keeping theheel firmly secured to the shoe or slipper because of the relative greatheight of the heel, causing considerable leverage strain to be placedupon the joint between the heel and the sole. Mechanical means forsecuring a heel to the sole have been proposed, but such devices havebeen so constructed as to seriously interfere with the steps ofassembling the shoe at the factory, or else have made necessary asubstantial undoing of work already finished, thereby addingconsiderably to the cost of production. Therefore, the principalobjectof this present invention is the provision of a mechanical securementwhich does not interfere with any of the manufacturing steps andprocedure now used in shoe factories, thereby keeping the cost down to aminimum, while another important object is the adaptability of theprinciple of this securement to heels of varying height.

In the drawing the upper portions of a shoe have been omitted forclearness, the sole portion of the shoe as shown comprising the insole iand the outsole 2. This sole combination is provided with an opening 3extending completely therethrough just above where the heel 4 islocated, said opening being rectangular or other shape as desired, andover this opening is positioned a metallic plate 5 provided centrallywith an oblong aperture 6 of dimensions to just permit passagetherethrough of the oblong head 1 of the screw 8. This screw head isformed to lie in a plane oblique to the axis of the screw as shown inFig. 1, the obliquity being in accordance with the angle made by theheel 4 with the heel portion of the sole. The portion of said plateadjacent each long side of the aperture 6 is depressed out of the planeof the plate to form the pockets 9 and I0 of a depth for receiving theends of the oblong head of said screw, as indicated in Fig. 4, thesepockets lying within the opening 3. One end wall of at least one ofthese pockets is formed substantially at right angles to the plane ofthe bottom of the pocket as indicated at H in Fig. l to establish anabutment against which an end of the screw head will contact to preventundesired 8, said bore having an enlarged portion it at 2 the bottom ofthe heel to receive therein a sleevelike nut ll whose flared head iscountersunk within the heel, as indicated at iii, to permit the top liftl9 to be applied and secured, as by the nail 20, in flush associationwith the surface of the heel. By this construction a definite shoulder2! is provided, where the bores i5 and i6 meet, against which the nutI'l will abut. A thin fiber or leather sheet 22 is provided to cover theplate 5.

From the foregoing description it will thus be apparent that, during themanufacture of the shoe, the plate 5 may be secured in place in theinsole in the insole cutting room and covered by the protective sheet22. After said plate is thus positioned the insole is nailed to the lastand goes through the lasting machine, sole laying, levelling, weltmachine, trimming machine, and then to the heeling department of thefactory, the pockets 9 and ID of said plate being so shallow that theywill not protrude through the combined sole structure to interfere withthese shoe treating and/or assembling operations.

Two or more short nails are driven by the wood heeler part way into thetop of a heel and their heads out off to provide a plurality of sharppegs, indicated at 25 in Fig. 2, which will enter the leather of thesole when the heel is applied thereto and aid in holding said heel inposition during the securing operation. The head of the screw 8 is thenpassed through the sole opening 3 and the oblong aperture 6 of the plate6, and. given a quarter turn to bring the head crosswise said aperturewith the ends of the head lying in the pockets 9 and I0, and one end ofthe head abutting the wall ll of a pocket. It will be understood thatthe shoe is still upon the last, and the latter supported with the soleof the shoe uppermost during these heel securing operations. Glue isthen applied over the top of the heel and/or over the heel seat, and theheel carefully applied to said seat with the screw 8 slipping throughthe bore l5. When correct registration is had, the heel is pressedagainst said seat whereupon the pegs 25 will enter the sole and preventthe heel from slipping out of alignment.

The shoe is then placed in a suitable machine by which necessarypressure is applied to make the heel and heel seat inseparably glued,then the nut 11 is inserted in the enlarged bore l6 at the bottom of theheel and threaded onto the screw 8 which is kept from turning by theengagement of the screw head and the wall ll of the plate pocket. Inthis operation the nut I! will ultimately abut tightly against theshoulder 2|, and continued turning will cause the screw 8 to furtherenter the nut thereby tightening the joint between the heel and thesole. After this operation the shoe is then removed from the pressuremachine since the heel is permanently fastened thereto, and the shoe isthen sent for attachment of the top lift I 9 after which the shoe isready for the packing room. In no case is the length of the nut i1greater than the depth of the larger bore I6, thereby insuring the toplift fitting smoothly over the head of said nut. All of the metallicparts are preferably made of strong rust-resisting material.

It is obvious that those skilled in the art may vary the details ofconstruction and arrangements of parts without departing from the spiritof the invention, and therefore it is desired not to be limited to theforegoing disclosure except as may be required by the claims.

What is claimed is:

1. In a shoe the combination oi. a sole; a heel; and means for-securingsaid heel to said sole, said means comprising a plate having a key slotand a pocket adjacent thereto, said pocket having an end wall disposedsubstantially at right angles to the plane of the bottom of the pocket,said plate disposed within the confines of the sole, and a memberprovided with a head having locking engagement with said key slot andpocket, an end of the head abutting the end wall of said pocket to limitthe movement of the head relative said plate, said member carried bysaid heel.

2. In a shoe the combination of a sole; a heel; and means for securingsaid heel to said sole, said means comprising a plate having a key slotand a pocket adjacent thereto, said pocket having an end wall disposedsubstantially at right angles to the plane of the bottom of the pocket,said plate disposed within the confines of the sole,
